FLYWHEEL GOVERNOR.

Original application filed March 9, 1921, Serial NO. 450,985. Dividedand this application filed January r27, 1922. Serial No. 532,285.

To all 'whom it 'may cmwer'n:

Be it known that we, RoY M. RoBINsoN and JAMEs BRADL-EY, citizens of theUnited States, residing at Albany, in the county of Albany and State ofNew York, have invented a new and Improved Flywheel Governor, of whichthe following is a specificatwn.

This invention has for its purpose to provide a new and improvedrotative member which, when used in connection with automotive Vehicles,takes ,the place of the usual fly 'wheel on the rear end of the crank orpower shaft and constitutes a flexible connection between the engine andits power application, like a transmission on a motor car power' unit.

Another and essential feature of this invention is the provision of afly wheel governor adapted for delivering or transmitting'power tomachinery m factories, 1n such manner whereby, as in starting individualmachines from a power line of shafting, the said rotative or fly wheelgovernor provides a ficxible means for taking up the load and impartingtransmission without jerk or slipping of belts or placing excessivestrain on the same.

As is well known,-motor cars possess,more

or less, crratic clutch engagement, also Vibration periods duringrotation of the crank shaft, which are caused by uneven pulsations, dueto the difference in power impulses of the several cylinders of themotor, which vibrations have not as yet, so far as we know, beensatisfactorily overcome.

This invention, among other purposes, is designed to eliminate thedisadvantages mentioned and it embodies a simple, relatively economicalconstruction of parts that present a practical means, useful as apu'lley for transmission of power, for providing an efiicient flexiblecoupling between a direct connected engine or motor and electric dynamoor generator, or in connection with an aeroplane propeller and itsdriving power, to take up the unequal thrusts 'of the blades as well asVibration.

With other minor objects in view, hereinafter apparcnt, this inventionis a combined fly wheel governor and vibration compensator, thatembodies the peculiar features of construction and novel combination ofVparts fully explained in the following detailed des'cription, asspecifically stated in the appended claims and illustrated in the accompanying draw-ring, in which:

Figure 1 is a face View.

fFigure 2 is a central Vertical section thereo In the embodiment' of ourinvention illustrated in the accompanying drawing, the parts areespecially designed for connection with the wheel 3 when it is intendedto be used as a fioating balance wheel to absorb vibration and balancethe impulses of an internal combustion engine.

In this form of the invention, 1 is the en- ,gine shaft which isprovided with a flange 12 having suitable holes through which bolts 4pass, the bolts 4 lying parallel with the axis of the shaft 1. The bolts4 also pass through the hub 21 of a Spider, the arms 20 of which -arepreferably pocketed, as at 90, to receive the ends of coil Springs 10which also seat in corresponding pockets in the lugs 8 of the flv wheel3, the fly wheel 3 having a hub 30 adapted to turn on the. hub 51 of theclutch member 52, the hub 51 being of a diameter less than that of theclutch member 52 and connected to it bv a web 51y between which web andthe hub 21 of the spider, the hub 30 of the fly wheel is movably fitted.The clutch member 52 is also provided with a flange 51z through whichthe bolts 4 pass and the bolts 4 are provided with nuts 53 by means ofwhich the parts 12, 21 and 51Z may be securely clamped together to moveas one with the shaft 1.

Tn the form of our invention illustrated in this application, it will beseen the wheel 3 is fioatably mounted on the hub portion 51 and, in thepractical arrangement, the said wheel and the driving Spider arefiexibly connected by suitable cushioning means, as for example thesprings 10, so that the balance wheel 3 absorbs and balances theimpulses imparted to the shaft 1.

The present application is a divisional part of our originalapplication'filed March 9, 1921, Serial No. 450,985.

'VVhat we claim is: i

1. In, mechanism o-f the Character described, a power shaft, a clutchhousing adapted to be clutch connected with a shaft to be driven, abalance wheel floatably 'mounted on the cluteh housing, a Spider shaft,al Spider frame including a hub aper-` tured to fit on the power shaft,means for securing said Spider frame hub and said clutch housing webtogether to Said power shaft fiange to rotate as a unit, a fiy wheelhaving a hub adapted to fit movably on said'clutch housing hub and heldbetween said clutch housing and said Spider frame hub, and fiexibleconnections between said fiy wheel and said Spider frame for absorbingshocks.
